Part Two API Development Chapter 3 API Overview Chapter 4 The COM API Chapter 5 Advanced API Development
Chapter 3 API Overview Section Overview This portion of the manual, Part Two, is intended to facilitate the development of custom user interfaces to the CineView Pro XL, CineView Pro and CineView Pro LE decoder boards using the Vela Application Programming Interface and the associated Software Developer’s Kit (SDK). It is assumed that the developer has a working knowledge of Microsoft Visual C++, COM, and programming in a Windows 2000 or NT environment.
66 CineView Pro Decoder Family 2.6 User Manual and API Guide destinations for the output video. The optional video FPGA will provide for audio embedding of up to 4channels and an LTC output. The Audio decoders are the Crystal CS4924 AC-3/Musicam decoders. The outputs of the decoders are sent to the CS8420 sample rate converters with built in AES transmitters. The bi-phase outputs of the sample rate converters are directly connected to the AES transformers.

76 CineView Pro Decoder Family 2.6 User Manual and API Guide A method is simply a public interface. The method will do something and will return a result code of some sort. To work well with COM, and with the future expansion into DCOM, every method call in our components returns an HRESULT return code. This return code should always be checked for validity and success of the function. The HRESULT is a 32-bit integer. Visual Basic will automatically intercept the error and go to an exception handler.
Chapter 4 — The COM API 77 CVProServer Class Properties A number of properties are available to the application developer to customize the behavior of the CineView Pro decoder.
